Boeing seeks U.S. anti-dumping probe vs. Bombardier

[peekay4]

That's one side of the story.

Here's the other side on the March 2012 Dispute Settlement Body ruling:

"In March of 2011 the WTO dismissed 80% of the total subsidy amounts the EU claimed, and in March of 2012 a WTO appellate panel upheld the earlier ruling. The WTO found $3.25 billion in subsidies to Boeing, noting that an additional $2.2 billion subsidy claim in the form of U.S. export tax credits had already been eliminated. Of the remaining subsidies, $2.6 billion were related to NASA R&D programs, $154 million to Defense R&D programs, and $500 million to state and local tax breaks. The USG complied with this ruling by the September 2012 deadline set by the WTO. NASA and defense R&D contacts were adjusted to secure commercial rights for the U.S. government (per the WTO ruling). Some of the tax breaks had expired and therefore are no longer relevant, and those that remain in place are too small to have a meaningful competitive impact on Airbus. In 2017 the WTO confirmed that Boeing had complied with virtually all of its rulings in this case."

According to Boeing, WTO found:

EU subsidies to Airbus: $22 billion. EU & Airbus have not complied with relevant WTO rulings.
US subsidies to Boeing: $3.5 billion. US & Boeing have complied to address all but $700 million of that amount, which is the amount under appeal.

That's an order of magnitude of difference between EU and US subsidies, according to WTO findings.

And now the focus is on Canada's alleged subsidies to Bombardier, and Bombardier's cross-border dumping (which is a separate issue from subsidies).
